StackAdapt

StackAdapt is an AI advertising platform covering connected television, digital out-of-home, email, direct mail, audio, video, native, display, in-game and ChatGPT advertising, with Ivy Studio, cross-channel attribution, a creative studio, client services, an API and a partner programme.

Cross-channel attribution is what a platform this broad has to get right, because the whole reason to buy connected television, audio, out-of-home and native from one supplier rather than four is to see how they contribute together, and without that the breadth is just procurement convenience.

Including direct mail alongside programmatic channels is a genuinely unusual combination and a shrewd one, since a physical piece arriving days after a digital sequence performs differently from either alone, and almost no platform can coordinate the timing between them.

Listing ChatGPT ads as a channel is the most forward-leaning item and should be read as a bet rather than an established practice, since advertising inside AI assistants is very new and neither the formats nor the measurement are settled. Regulated industries including political, healthcare and finance are named separately, which reflects the compliance overhead each carries. StackAdapt keeps its rates behind a plans and packages page.
